there is a problem with laptops which have Intel CPU + GTX 1050/1050Ti/1060/1070/GT 640M. The problem is, whenever you try to do some action on the OS, discrete GPU is triggered and it causes a 0.5s freeze.

Some actions, which cause the dGPU to wake up and lock up the whole system for about 0,5 seconds are:

The problem can be found on all laptop brands: ASUS, Acer, Clevo, Dell, Gigabyte, HP, Lenovo, MSI, Razer.The problem can be solved by either disabling Intel GPU, which forces the system to always work with NVIDIA, or disabling NVIDIA GPU. Both of them is not an option though, as if you disable Intel, not only you will drain the battery faster, but also some games will stop working. If you disable NVIDIA, then what is the point of buying a laptop with a discrete GPU?There is a also a workaround: configuring TrayPwrD3 to always work with NVIDIA in the backgound. This keeps the NVIDIA GPU alive but also drains battery faster. And there is no poaint in that as it renders Optimus useless!So, manufacturers have to come up with a fix.Thank you.

I believe we have root caused the issue and are testing various potential fixes, one looking promising so far. This happens often though in fixing bugs, we'll attempt to check in and hopefully it won't cause other issues or break when combined with other code fixes. It is a step in the right direction though and I thought I'd share progress. If all goes well, we could be looking at a fix in our March/April driver depending on any complications and perhaps a Beta if I can get one out sooner. I'll keep the updates coming as they're available.

Please provide steps to replicate the issue. These steps are very crucial to finding the root cause and fix.A screenshot to illustrate the issue is a huge plus. A video of the failure is even better! Attach to the post or provide the YouTube link.

You have Intel HD 630 + NVIDIA GTX 1060 laptop. You right click on desktop and the system freezes for a second. You click on battery icon, system freezes again. I saw no freeze and NVIDIA GPU in your videos...

But I really aprreciate Intel's approach to the topic. Al least you are trying to help unlike Microsoft.

Thank you for the answer provided, coolrecep, let me check, I will continue to look for a system with hybrid graphics (Intel + dedicated graphics adapter) to perform the tests and proceed accordingly looking for a solution.
